Hinokiflavone is a novel modulator of pre-mRNA splicing activity extracted from plants with anti-inflammatory, anti-tumor and antiviral activities. Hinokiflavone is also a potent inhibitor for matrix metalloproteinases (MMPs). Hinokiflavone attenuates the virulence of Methicillin (HY-121544)-resistant staphylococcus aureus by inhibiting caseinolytic protease P (ClpP) with an IC50 value of 34.36 mg/mL. Hinokiflavone induces apoptosis via the reactive oxygen species-mitochondria-mediated apoptotic pathway and inhibits tumor cell migration and invasion. Hinokiflavone is a SUMO protease inhibitor against sentrin-specific protease 1 (SENP1) activity[1][2][3]. | [Definition]
ChEBI: A biflavonoid that is apigenin substituted by a 4-(5,7-dihydroxy-4-oxo-4H-chromen-2-yl)phenoxy group at position 6. A diflavonyl ether, it is isolated from Rhus succedanea and has been found to possess significant cytotoxic
otential. | [Biological Activity]
Hinokiflavone is a plant biflavone th at exhibit potent anticancerhepatoprotectiveantibacterialantiviraland anti-inflammatory activities. Hinokiflavone induces apoptosis and cell cycle arrestand blocks migration and invasion of melanoma cells. It is a potent inhibitor of dengue 2 virus RNA-dependent RNA polymerase (DV-NS5 RdRp). Hinokiflavone is a modulator of pre-mRNA splicing in cells. It increases SUMOylation of a subset of spliceosome proteins by inhibiting SENP1 protease activity. It induces apoptosis in esophageal squamous cell carcinoma (ESCC) through regulation of PI3K/AKT/mTOR pathway. | [in vivo]
Hinokiflavone (25 or 50 mg/kg, i.p., daily for 24 days) has antitumor activity via suppressing tumor proliferation, metastasis and inducing Apoptosis in CT26 tumor-bearing mice[2].
Hinokiflavone (100 mg/kg, s.c., every 12 h for 96 h) shows a protective effect on pneumonia infection by Improving survival rate in mice[3].
| Animal Model: | CT26 tumor-bearing mice model[2] | | Dosage: | 25 or 50 mg/kg | | Administration: | i.p., daily for 24 days | | Result: | Resulted in retarded tumor progression and reduction of tumor weight without affecting body weight of mice, suppressed tumor proliferation and invasion ability by staining nuclear Ki-67 and MMP9, induced the apoptosis by staining cleaved caspase-3. |
